BACKGROUND 1. Field of the Invention

Example embodiments of the invention relate to a portable smart hand grip. More particularly, example embodiments of the present invention relate to a portable smart hand grip which is capable of determining degree of sarcopenia of a user, and is used for an integrated health management system that provides feedback for correcting exercise methods and behavior according to the degree of sarcopenia.

2. Related Art

Sarcopenia, in which the amount of muscle, muscle strength, and muscle function are all reduced, is a musculoskeletal disease, which causes various cardiovascular and metabolic diseases in addition to fall accidents, resulting in high medical expenses. In particular, in the case of medically vulnerable groups such as low-income seniors living alone, because they cannot afford to take care of themself through exercise due to the hardship of life, the sarcopenia may cause a social problem that worsens their financial or health status with various diseases.

On the other hand, in muscle strength, a force of gripping an object with a hand is referred to as a grip strength. Such grip strength is used as an index for evaluating a metabolic change of muscles and body muscle mass, and for evaluating success or failure of a rehabilitation treatment program. That is, the grip strength is used an index for comprehensively evaluating the user's health status. When the grip strength falls below the reference value, the probability of occurrence of disability increases. Furthermore, the risk of death increases, so it is good to exercise to maintain or improve the grip strength as you get older.

Various types of hand grips are used for exercise. Especially, a small portable hand grip is widely used. However, such small portable hand grip does not have any additional functions other than the advantage of being able to perform grip exercises.

Accordingly, various types of hand grippers combined with electronic devices that implement a function of measuring grip strength or a function of transmitting and receiving grip strength measurement related data have been proposed, but such hand gripper has a conventional structure of general hand grip with complicated structure and poor portability.

SUMMARY

The purpose of the invention is providing a portable smart hand grip that can be linked with a smartphone and transmits a user's muscle strength data to a management server, and based on this, enables integrated health management of the user, has a simple structure, and is easy to carry.

According to an example embodiment of the invention, a portable smart hand grip includes a first housing, a guide part combined with the first housing and comprising a first receiving portion and a second receiving portion, a second housing facing the first housing and having a first pressing portion and a second pressing portion which are received in the first receiving portion and the second receiving portion, respectively, a first elastic member disposed between the first pressing portion and the first housing, a second elastic member disposed between the second pressing portion and the first housing, a sensor received in the first housing for detecting a user's operation of the portable smart hand grip, a control circuit unit received in the first housing to control an operation of the sensor, and a battery unit received in the first housing to provide power to the control circuit unit.

In an example embodiment, the portable smart hand grip may further include a plate part combined with the second housing. A first opening and a second opening may be formed through the plate part, the first pressing part extends toward the second housing through the first opening. The second pressing part may extend toward the second housing through the second opening. When the first housing and the second housing come close to each other by the user's operation of the portable smart hand grip, the first receiving part and the second receiving part may be disposed in the first opening and the second opening of the plate part.

In an example embodiment, the plate part may be slidably coupled to the second housing. A first push switch and a second push switch may be formed at both ends of the plate part in a direction in which the plate part slides. A fixing protrusion receiving portion may be formed at the plate part. A fixing protrusion may be formed on the guide part. The fixing protrusion receiving portion may include a first opening portion and a second opening portion connected to the first opening portion. A width of the second opening portion may be smaller than a width of the first opening portion. When the first housing and the second housing come close to each other by the user's operation of the portable smart hand grip, the fixing protrusion may be received in the first opening portion, and the plate part may slide by pressing the first or second push switch of the plate part, and the fixing protrusion may be received in the second opening portion. Therefore, the first housing and the second housing may be locked to each other.

In an example embodiment, a charging terminal receiving portion protruding toward the first housing may be formed at the guide part, a charging terminal for charging the battery unit may be exposed on a side of the charging terminal receiving portion. An opening for receiving the charging terminal receiving portion may be formed in the plate part. When the first housing and the second housing come close to each other by the user's operation of the portable smart hand grip, the charging terminal receiving portion may be received in the opening of the plate part.

In an example embodiment, the first and second elastic members may be each a spring. The sensor may be a photo sensor and located adjacent to the spring. A sensor recognition part may be protruded from the first pressing part. When the first housing and the second housing come close to each other by the user's operation of the portable smart hand grip, the sensor recognition unit may pass through the spring and the photo sensor may recognize the user's operation.

In an example embodiment, the sensor may include a first sensor and a second sensor disposed adjacent to each other. When the first housing and the second housing come close to each other by the user's operation of the portable smart hand grip, the first sensor and the second sensor may sequentially recognize the user's operation. When only the first sensor recognizes, it may be recognized that the user has operated the portable smart hand grip with a weak grip force, and when both the first sensor and the second sensor recognize, it may be recognized that the user has operated the gripper with a strong grip force.

In an example embodiment, the sensor may be a Hall sensor for measuring magnetic force. A magnet may be attached on the first pressing part. When the first housing and the second housing come close to each other by the user's operation of the portable smart hand grip, the Hall sensor may sense the magnetic force of the magnet and recognizes the user's operation and strength of a grip force.

In an example embodiment, wherein the sensor may be a push button switch including a switch button. When the first housing and the second housing come close to each other by the user's operation of the portable smart hand grip, a pressing part guide connected to the first pressing part may press the switch button so that the user's operation can be recognized.

In an example embodiment, the control circuit unit may further include a communication unit for communication with an external device and a vibration motor. The communication unit may transmit a measurement data detected by the user's operation or a data calculated therefrom to the external device through a smartphone or a network. A feedback for an exercise method and behavior correction according to the user's degree of sarcopenia is informed to the user by vibration intensity and frequency of the vibration motor.

According to the example embodiment of the invention, the portable smart hand grip has a simple structure, can be implemented at a low cost, and easy to carry. The portable smart hand grip may be used in an integrated health management system that provides feedback for correcting an exercise method and behavior according to the user's degree of sarcopenia.

In particular, in the case of the elderly who are vulnerable to sarcopenia, it is not easy to carry a gripper because it is not habitual to carry smart devices. In the case of the portable smart hand grip, the first housing and the second housing are compressed and locked together in a portable mode, so that it can be easily carried in a small space such as a pocket. Especially, by applying the plate part of a sliding type, in which the fixing protrusion and the fixing protrusion receiving portion are formed, even if an elastic member with strong elastic force is used, they can be firmly locked.

In addition, even if a waterproof and dustproof design or parts are not used, a living waterproof level is possible in a portable mode that the portable smart hand grip is compressed and locked.

In addition, by sending various muscle strength related data of the user measured through the portable smart hand grip to an external server, an integrated health management system that provides feedback for correcting exercise methods and behavior according to the degree of sarcopenia may be provided.

However, the effects of the present invention are not limited to the above effects, and may be variously expanded without departing from the spirit and scope of the present invention.

The present invention may, however, be embodied in many different forms and should not be construed as limited to the example embodiments set forth herein. Rather, these example embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art. Like reference numerals refer to like elements throughout the accompanying drawings.

Example Embodiment

FIG. 1 is a combined perspective view illustrating an ornament assembly according to an example embodiment of the present invention.

FIG. 1 is an exploded perspective view illustrating a schematic structure of a portable smart hand grip according to an example embodiment of the present invention. (a) and (b) of FIG. 2 are perspective views respectively illustrating when the portable smart hand grip of FIG. 1 is expanded and compressed. (a), (b) and (c) of FIG. 3 are cross-sectional views respectively illustrating when the portable smart hand grip of FIG. 1 is expanded, compressed, and locked in a portable mode.

Referring to FIGS. 1 to 3 , the portable smart hand grip may include a first housing 100, a guide part 150, a first elastic member SP1, a second elastic member SP2, a second housing 200, a plate part 250, a control circuit part CP, and a sensor CS and a battery unit BP.

The first housing 100 may receive the control circuit unit CP, the sensor CS, and the battery unit. The first housing 100 can house an electronic equipment that makes up the portable smart hand grip. The first housing 100 may have an elliptical boat shape having a long direction in a first direction D1 and a short direction in a second direction D2 perpendicular to the first direction D1.

The guide part 150 may be combined with the first housing 100. The guide part 150 may include a first receiving portion 152 and a second receiving portion 154. The guide part 150 may cover an open upper portion of the first housing 100 opened in a third direction D3 perpendicular to the first direction D1 and the second direction D2. The first receiving portion 152 may be formed in a cylindrical shape with an open top to receive the first elastic member SP1 therein. The second receiving portion 154 may be formed in a cylindrical shape with an open top to receive the second elastic member SP2 therein.

A charging terminal receiving portion 156 may be further formed at the guide part 150. The charging terminal receiving portion 156 may be protruded toward the first housing 100, that is, in the third direction D3, on the guide part 150, a charging terminal PW for charging the battery unit BP may be exposed on a side of the charging terminal receiving portion 156. The charging terminal PW may be a USC-C port, etc., an external power source may be connected to the charging terminal PW to charge the battery unit BP.

When the portable smart hand grip is compressed and the first housing 100 and the second housing 200 are close to each other, the charging terminal PW and the charging terminal receiving portion 156 are not exposed to the outside because they are accommodated in the second housing 200 through a first opening OP1 of the plate part 250 which will be described later. Accordingly, even if a waterproof and dustproof design or parts are not used for the charging terminal PW, a living waterproof level is possible in a portable mode that the portable smart hand grip is compressed and locked. (See (c) of FIG. 3 )

A fixing protrusion 158 may be formed on the guide part 150. The fixing protrusion 158 may be formed to protrude from the guide part 150 toward the first housing 100, that is, in the third direction D3. The fixing protrusion 158 may include an extending portion extending from the guide part 150 and a head portion formed at an end of the extending portion and having a width greater than a width of the extending portion.

The first elastic member SP1 may be disposed between a first pressing part 210 which will be described later and the first housing 100. The first elastic member SP1 may be a spring. On the other hand, by replacing a spring having a desired degree of elasticity, the portable smart hand grip can have a desired degree of elasticity.

the second elastic member SP2 may be disposed between a second pressing part 210 which will be described later and the first housing 100. The second elastic member SP2 may be a spring. The second elastic member SP2 may be substantially the same as the first elastic member SP1.

The second housing 200 may be placed opposite the first housing 100. The second housing 200 may have an elliptical boat shape having a long direction in the first direction D1 and a short direction in the second direction D2. Therefore, the second housing 200 may have an overall symmetrical shape with the first housing 100.

The second housing 200 may be formed with the first pressing part 210 and the second pressing part 220 received in the first receiving portion 152 and the second receiving portion 152, respectively. A first pressing part guide 212 may be formed at the first pressing part 210, and the first pressing part 210 may be configured to be slidable along an inner peripheral surface of the first receiving portion 152. A second pressing part guide 222 may be formed at the second pressing part 220, and the second pressing part 220 may be configured to be slidable along an inner circumferential surface of the second receiving portion 154.

The first pressing part 210 may have a sensor recognition unit 214 formed therein. The sensor recognition part 214 may be formed in a form of a protrusion protruding in an opposite direction which is opposite to the third direction D3 at an end of the first pressing part 210 in the opposite direction.

The plate part 250 may be slidably coupled to the second housing 200. A first opening OP1 and a second opening OP2 may be formed through the plate part 250.

The first pressing part 210 may extend toward the second housing 200 through the first opening OP1. The second pressing part 220 may extend toward the second housing 200 through the second opening OP2.

When the first housing 100 and the second housing 200 come close to each other by the user's operation, the first receiving portion 152 and the second receiving portion 154 may be received in the first opening OP1 and the second opening OP2 of the plate part 250.

A first push switch 262 and a second push switch 264 may be formed at both ends of the plate part 250 in a sliding direction of the plate part 250, that is, in the first direction D1.

The plate part 250 may further have a fixing protrusion receiving part 250 formed therein. The fixing protrusion receiving portion 250 may include a first opening portion 252 a and a second opening 252 b which has a width smaller than that of the first opening portion 252 a.

When the first housing 100 and the second housing 200 come close to each other by the user's operation of the portable smart hand grip, the fixing protrusion is received in the first opening portion, and the plate part 250 slides by pressing the first push switch 262 of the plate part 250, and the fixing protrusion 158 is received in the second opening portion 252 b, therefore the first housing 100 and the second housing 200 are locked to each other.

Accordingly, the portable smart hand grip can be easily carried by occupying only a small volume when not in use. Also, for using the portable smart hand grip again, the second push switch 264 can be pressed and the fixing protrusion 158 is separated from the second opening portion 252 b, and then the locking state is released, and the portable smart hand grip can be used again. (Refers to (a) to (c) of FIG. 3 )

The plate part 250 may have an opening for receiving the charging terminal receiving portion 156. When the first housing 100 and the second housing 200 come close to each other by the user's operation, the charging terminal receiving portion 156 may be received in the opening of the plate part 250. In the present example embodiment, the opening has a shape in which the first opening OP1 is extended.

The sensor CS may be disposed within the first housing 100. The sensor CS may detect the user's operation of the portable smart hand grip. For example, the sensor CS may be a photo sensor that detects light or other electromagnetic waves and may be located adjacent to the first elastic member SP1.

When the first housing 100 and the second housing 200 come close to each other by the user's operation of the portable smart hand grip, the sensor recognition part 214 passes through the elastic member SP1 (which is a spring) and the photo sensor, so that the user's operation of the portable smart hand grip can be recognized through the photo sensor.

According to another embodiment, the sensor CS may be a Hall sensor, and a magnet may be attached to the first pressing part 210 instead of the sensor recognition part 214. The Hall sensor may recognize a proximity of the magnet. Accordingly, the user's operation of the portable smart hand grip may be recognized. The Hall sensor is a sensor that detects a direction and magnitude of a magnetic field by using a Hall effect in which a voltage is generated in a direction perpendicular to a current and a magnetic field when the magnetic field is applied to a conductor through which the current flows. Since the Hall sensor senses the magnetic force of the magnet, it is possible to recognize the user's operation and strength of the operation of the portable smart hand.

The control circuit unit CP may control an operation of the sensor. The battery unit BP may supply power to the control circuit unit CP.

The control circuit unit CP may be disposed in the first housing 100 and receive a signal from the sensor CS so that the user's grip strength can be measured. In order to measure the grip strength, the control circuit unit CP may count the number of times the user operates the portable smart hand grip, measure an interval between the user's gripper operation, or measure a holding time during which the gripper operation is maintained. The control circuit unit CP may include a communication unit for communication with an external device, and may transmit measured data or data calculated therefrom to an external device through a smartphone (not shown) or a network (not shown). In addition, the control circuit unit CP may further include a GPS module (not shown) for measuring the user's location.

The control circuit unit CP, by using the signal received from the sensor CS, may count the number of times of the user's grip exercise. Also, the control circuit unit CP may measure a period or an interval between a peak and an adjacent peak based on the interval between the peaks of the signal received from the sensor CS. Also, the control circuit unit CP may calculate the time that the user maintains compression state with respect to the portable smart hand grip,

Here, a grip force data measured during the user's grip force exercise includes grip force exercise number information, interval information, and holding time information. In addition, the grip force data further includes a total exercise time, a degree of elasticity of the elastic member used, and the like. The grip force data may be transmitted to an external device by the communication unit, and the external device may determine whether the user has sarcopenia based on the grip force data, and provide feedback thereto.

The control circuit unit CP, including a vibration motor, a speaker, and the like, may give feedback necessary to the user. For example, when the grip force exercise of the appropriate intensity is completed, the user may be notified of the end of the grip force exercise by the vibration of the vibration motor. In addition, when the grip force of an appropriate intensity is maintained, a success of the grip force exercise may be notified by the vibration of the vibration motor to notify the user of the success of the grip force exercise.

The portable smart hand grip according to the present invention can be used in an integrated health management system that determines the degree of sarcopenia, and provides feedback for exercise method and behavior correction according to the user's degree of sarcopenia.

That is, the portable smart hand grip transmits the measured user's muscle strength data to the user terminal, and based on the muscle strength data, it is possible to provide a customized exercise program according to the user's strength level. Furthermore, it is possible to monitor the sarcopenia disease, and also to induce behavioral correction of the user's lifestyle.

Although not shown, the portable smart hand grip may further include a status display unit in a form of a display, a switch for on/off of power, or the like, or a wake-up algorithm may be applied to the portable smart hand grip. For example, when the user's operation is not detected for more than a preset time, it may be set to enter a power saving mode, and the power saving mode is released by the user's operation,

(a) and (b) of FIG. 4 are cross-sectional views respectively illustrating when a portable smart hand grip according to an example embodiment of the present invention is expanded and compressed.

Referring to (a) and (b) of FIG. 4 , the portable smart hand grip may be substantially the same as the portable smart hand grip of FIGS. 1 to 3 , expect for including a first sensor CS1, a second sensor CS2 and a third sensor CS3 instead of one sensor. Therefore, repeated description is omitted.

The first sensor CS1, the second sensor CS2, and the third sensor CS3 may be disposed in the first housing 100 and may be sequentially disposed in a direction opposite to a third direction D3. As the sensor recognition unit 214 moves in the opposite direction to the third direction D3 by the user's grip operation, a sensor recognition unit 214 moves in the opposite direction to the third direction D3 and sequentially passes through the first sensor CS1, the second sensor CS2, and the third sensor CS3. Through the detection signals of the first to third sensors CS1, CS2, and CS3, not only the number of grip operation but also the strength of the grip force may be measured.

In this embodiment, three sensors arranged in sequence are used, but it is sufficient to apply two or more sensors in order to measure the strength of the grip force of the grip operation, and an appropriate number of sensors may be applied as necessary.

For example, when two sensors are applied, when the first housing 100 and the second housing 200 come close to each other by the user's operation, a first sensor and a second sensor sequentially recognize the user's grip operation. When only the first sensor recognizes, it can be recognized that the user operated the portable smart hand grip with a weak grip force. when both the first sensor and the second sensor recognize, it can be recognized that the user has operated the portable smart hand grip with a strong grip force.

FIG. 5 is a cross-sectional view illustrating a schematic structure of a portable smart hand grip according to an embodiment of the present invention. (a), (b) and (c) of FIG. 6 are partially enlarged cross-sectional views for explaining an operation of first to third switches according to a degree of compression of the portable smart hand grip of FIG. 5 .

Referring to FIGS. 5 and 6 , the portable smart hand grip may be substantially the same as the portable smart hand grip of FIG. 4 , except that each of sensors CS1, CS2 and CS3 is a push button switch including a switch button SW1, SW2, SW3, and a pressing part guide 212 of a first pressing part 210 formed inside of a first receiving part (refers to 152 of FIG. 1 ) works as a sensor recognition. Therefore, repeated description is omitted.

When the portable smart hand grip is compressed and a first housing 100 and a second housing 200 are close to each other, the pressing part guide 212 connected to the first pressing part 210 sequentially presses the switch buttons SW1, SW2, SW3, so that the user's operation can be recognized. In this embodiment, the three sensors CS1, CS2, and CS3 are applied to measure not only the number of grip operation but also the strength of the grip force like the portable smart hand grip of FIG. 4 . However, it is also possible to use only two sensors or to measure only the number of grip operation using only one sensor, like the portable smart hand grip of FIGS. 1 to 3 .

(a) and (b) of FIG. 7 are perspective views respectively illustrating when a portable smart hand grip according to an embodiment of the present invention is expanded and compressed.

Referring to FIG. 7 , the portable smart hand grip is substantially the same as the portable smart hand grip of FIGS. 1 to 3 , expect that two fixing protrusions 158 a and 158 b are formed, the charging terminal receiving part 156 is formed between the first receiving part 152 and the second receiving part 154. The overall shape of the first housing 100 and the second housing 200 is a bar shape. Therefore, repeated description is omitted.

According to the example embodiment of the invention, a portable smart hand grip includes a first housing, a guide part combined with the first housing and comprising a first receiving portion and a second receiving portion, a second housing facing the first housing and having a first pressing portion and a second pressing portion which are received in the first receiving portion and the second receiving portion, respectively, a first elastic member disposed between the first pressing portion and the first housing, a second elastic member disposed between the second pressing portion and the first housing, a sensor received in the first housing for detecting a user's operation of the portable smart hand grip, a control circuit unit received in the first housing to control an operation of the sensor, and a battery unit received in the first housing to provide power to the control circuit unit.

The portable smart hand grip has a simple structure, can be implemented at a low cost, and easy to carry. The portable smart hand grip may be used in an integrated health management system that provides feedback for correcting an exercise method and behavior according to the user's degree of sarcopenia.

In particular, in the case of the elderly who are vulnerable to sarcopenia, it is not easy to carry a gripper because it is not habitual to carry smart devices. In the case of the portable smart hand grip, the first housing and the second housing are compressed and locked together in a portable mode, so that it can be easily carried in a small space such as a pocket. Especially, by applying the plate part of a sliding type, in which the fixing protrusion and the fixing protrusion receiving portion are formed, even if an elastic member with strong elastic force is used, they can be firmly locked.

In addition, even if a waterproof and dustproof design or parts are not used, a living waterproof level is possible in a portable mode that the portable smart hand grip is compressed and locked.

In addition, by sending various muscle strength related data of the user measured through the portable smart hand grip to an external server, an integrated health management system that provides feedback for correcting exercise methods and behavior according to the degree of sarcopenia may be provided.

The foregoing is illustrative of the invention and is not to be construed as limiting thereof.
